How do I deal with my husband's anger and resentment toward my family after my father's stroke?

How do I deal with my husband's anger toward my family after my father's stroke? He resents their lack of help and I bear the brunt of his extreme anger . He makes very negative statements each day. If I am very tired or sad about my father's condition, I am sometimes reduced to tears. I have a large family, but I am the only person who is near enough to help on a daily basis. My father's strokes occurred on Christmas Day and he has been in hospitals and acute care units that may require up to a 1 hour drive.I do not think my family helps enough but my mother is 82 with a TBI from 3 years ago. My father is 84. My older sister is over 60 and lives 8 hours away. One brother travels and the other, a doctor, lives two hours away but tries to help constantly. I love my father very much and do not mind juggling my husband and son, my father, and my teaching job. I know vacation is in 18 days and I can make it. My husband makes comments about never wanting to see or interact with my family although he has been kind to my father. He badgers me with critical comments about my family . What should I do? I can't make them help.
